v SPECIFICA'I'IfiDN'.

TO ALL WHOM IT MAY CONCERN p l i a Be it known that I, DE FIGANIERE, of Philadelphia, in the county of Philadelphia, andState of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Super-Phosphate of Lime; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art toamake and use the same, reference being had to the accompanying drawingspforming part of this specification, in whichp l i Figure 1 is avertical section of my improved apparatus for moistening the guano or other fertilizer with 1, sulphuric acid, taken through the line x,-x, fig. 2. p l i Figure 2 is a top view of the same.v

Similar letters of reference indicate lihe'parts. l. a l j V y My invention has for its object to-improve the manufactureofsuper phosphate of lime, by the more thorough incorporation of the acid with the guano or other fertilizer, than can be donewhen theroperation is performed by hand labor in the manner heretofore practised. And it consists, first, in,makingthesuper-phosphate of lime by bringing powdered guano or any other suitable fertilizing material into contact witha surface covered orfl t dampened with sulphuric acid. And second, in the apparatus by means of which this isac complislie d said apparatusbeing formed by the combination of an acid tank, revolving cylinder, hopperand scraper, with each other, as hereinafter more fully described. I p p In the manufacture of super-phosphate of lime, as heretofore practised: the sulphuric acid has been incorporated with the guano or other fertilizer by hand labor, and consequently they have not been thoroughlyand a i uniformly mixed. In preparing the super-phosphate according to my improved method, the acid and fertilizer areuniformly mixed, To accomplish this, I. use the apparatus hereinafter described but 'the'same resultdmayi 1 a be obtained by the use of various other apparatus, and consequently Ido not limit myself exclusively to the use p of this. i *5 i i p y i A is the tank in which the sulphuric acid is placed, the size of which must depend upon the amountof work; i l to be done. To the sides of thetank, A, are secured the supports, B, in which are formed the bearings fon the a 1 journals of the cylinder, C. One of the journals of the cylinder C extends outward, and upon it is formed or to, it is attacheda crank, D, or a pulley, by means of which motion is given to the said cylinder. x To theupper end r of the supports B, is attached a hopper, E, the discharging orifice of which is directly over the fac e of the cylinder G, and a little to that side of the vertical central line of said cylinder towards which it revolves. The: l j powdered guano or other fertilizer is placed in the hopper E, and flows through the opening at its bottom upoii the surface of the cylinder 0, which iskept constantly wet with sulphuric acid by revolving through the acid in H the tank A. The moistened fertilizer is removed from the surface of the cylinder G, by the scraper I, whi h l also acts as a spout to conduct it to the receptacle prepared forits reception. The flow of the powdered material 1 r from the hopper E, may be regulated by a damper placed in the said hopper in, the ordinary manner, and the amount of acid supplied by the cylinder C, may be regulated at pleasure by regulating thclvelo city of its rcvjolution. By this processI am able to furnish a superior super-phosphate and at the sametiuie to ecouomize laborr and time in its preparation- 1 t i i t What I claim as new, and desire to secure by Letters Patent, isl p r 1 p p 1. Making super-phosphate of lime, by bringing the powdered guano, or other suitable fertilizingmaterial,into, contact with a surface covered or dampened with sulphuric acid, substantially, aslherein described; f i i a y 2. An apparatus for incorporating sulphuric acid with powdered uano, or other suitable fertilizer, formed stantially as herein shown and described.-
